The treatability of stabilized sanitary landfill leachate via synthetic anion exchange resin (INDION FFIP MB) was investigated. An ideal experimental design was conducted based on central composite design using a response surface methodology to assess individual and interactive effects of critical operational variables (i.e., anionic dosage; contact time; shaking speed) and pH on treatment performance in terms of color, chemical oxygen demand (COD), suspended solid (SS), and turbidity removal efficiencies. Optimum operational conditions were established as 30.9 cm(3) anionic dosage, 90 min contact time, 150 rpm shaking speed, and pH 3.1. Under these conditions, the color, COD, SS, and turbidity removal efficiencies of 91.5, 70.3, 93.1, and 92.4% were experimentally attained and were found to fit well with the prediction model. According to these results, stabilized leachate treatment using INDION FFIP MB could be an effective alternative in the administration of color, COD, SS, and turbidity problems of landfill leachates.
采用合成阴离子交换树脂（INDION FFIP MB）对稳定化卫生填埋场渗滤液的可处理性进行了研究。基于中心复合设计，采用响应面法，对关键操作变量（即阴离子剂量、接触时间、搅拌速度）和 pH 值对颜色、化学需氧量（COD）、悬浮物（SS）和浊度去除效率的单独和交互影响进行了评估，设计了理想的实验。根据处理性能，确定了最佳操作条件为：阴离子剂量 30.9cm(3)、接触时间 90min、搅拌速度 150rpm、pH 值 3.1。在这些条件下，实际达到的颜色、COD、SS 和浊度去除效率分别为 91.5%、70.3%、93.1%和 92.4%，与预测模型拟合良好。根据这些结果，使用 INDION FFIP MB 处理稳定化渗滤液可能是管理填埋场渗滤液颜色、COD、SS 和浊度问题的有效替代方法。
